Introduction
If your dishwasher runs yet won’t heat up, chances are the heating element has gone bad. To tell if your dishwasher heating element is bad, you can check for signs of corrosion, listen for a humming sound, and test the element.
Signs of Corrosion
Check the heating element for signs of corrosion or damage. If it’s corroded or has visible cracks or damage, it likely needs to be replaced. Corrosion can occur when the dishwasher has been exposed to too much moisture, leading to rust and sparking.
Humming Sound
Listen for a humming sound when the dishwasher is running. If the heating element is bad, it may make a humming sound when it’s trying to heat up.
Testing the Element
To test the element, unplug the dishwasher and remove the lower access panel. Use a multimeter to measure the resistance of the heating element. If the resistance is too low, or if the multimeter reads “open,” then the element is bad and needs to be replaced.
